WILLIAM L. GROOM, OF COAL VALLEY, ALABAMA.

COMBINED MINING AND TRACK TOOL.

Specification of Letters-Patent.

Patented Feb. 2, 1909.

Application filed October 5, 1907. Serial No. 396,040%.

To all whom it may concern:

Be it known that I, \VILLIAM L. GRoo ment of the construction of a tool or pick,

which comprises a minimum number of parts, is comparatively simple in structure, and very eflicient in operation.

With this and other objects in view, the invention consists of certain novel constructions, combinations, and arrangements of parts, as will behereinafter fully described and claimed. i

In the drawings: Figure 1 is a view in side elevation, partly in section, of a tool or pick constructed in accordance with the present invention. Figs. 2 and 3 are views similar to Fig. 1, showing the different kinds of tools secured to the head of the tool or pick. Fig. 4 is a sectional view taken on line 4, 4 Fig. 1. of the pick or tool as it appears in operation.

Referring to the drawings by numerals, 1 designates the body of the'head, which is provided with ends 2, and with a handle-rejceiving portion 3.

Each end 2 is provided with preferably, a square socket 4; a set-screw 5 is threaded into each end, and is adapted-to have its inner end extend into the socket 4. I

The head is provided on the side opposite to the handle-receiving portion 3, or, in other words, upon its outer face, with an outwardly bulged or curved reinforcing guard 6, which is integrally connected at its ends to the end portions 2 of the body, and

the guard 6 is provided with an enlarged, central opening or aperture ,7 for facilitating the insertion of the handle 8 into the head; the handle 8 being normally positioned in the longitudinally extending opening or aperture 9, which extends through the body of the head. After the handle 8 has been placed in the opening or aperture 9, a suitable wedge or fastening member 10, Fig. 4, may be driven into the inner end of the hen Fig. 5 is a view, in side elevation,

' dle through aperture 7, of the outwardlycurved or bulged guard or flange 6 for securing the handle in position.

The outwardly-curved or bulged guard or flange 6 increases the strength of the pickhead, although it decreases the amount'of material used in the construction thereof; it will be seen that there is left an elongated slot or opening 11 between the body of the head and the guard or flange 6; furthermore, as seen in Fig. 5, when the pick is in use, and

it is desired to pry up a load, the outwardlybulged guard or flange 6 will facilitate this operation, as it acts as a fulcrum or bearing point for assisting the detachable oints 12 in raising or moving the load, whic may be a piece of ore or coal or a tie, as indicated,

as at 13.

The pickpoints 12 are detachably secured in the sockets 4 by means of the setscrews 5 and can be quickly detached, when it is desired to substitute therefor a difi'erent kind of a tool.

To minimize the cost of construction of the pick-head, the portion 3 is comparatively thin, although it is greatly reinforced by having the portions 14 of the body extend inward, producing a V-shaped rein forcing rib 15'upon each side of the body, thereby materially strengthening the body and also preventing the portion 3 from being easily broken, for the reason that if the side of the head comes in contact with a foreign object, the object will strike against a rib 15 and prevent the object from hitting the thin or reduced portion of the head. Therefore, it is to be noted that by reason of my peculiarly-constructed reinforcing ribs 15 and the outwardly-bulged flange or portion 6, I have provided a very light head that is durable and efiicient in operation.

In Fig. 2, I have shown a hammer 16, rovidedwith a squared shank 17; the shan 17 being positioned in one of the sockets 4 and engaged by set-screw 5. In the opposite socket 4 of the head, is positioned a squared shank 18 of an adz, which adz is provided with a curved blade 19 terminating in a body the strain is often greater upon the shoulder 22, as the blade 19 engages'an object.

In Fig. 3, I have shown a hatchet, secured to one of the ends 2, and said hatchet comrises a blade 23 and a shank 24 the shank eingpositioned in the socket and secured by means of a set-screW 5.

The aperture or opening 7 in the out- Wardly-bulged guard is, preferably, larger than the aperture 9 for facilitating the position of the handle in the head,but said aperture does not materially neaken the guard, for the guard can be formed as thick as desired, beside the lever function of the guard w ill be performed when the tool is in use.

The operator can carry a number of different kinds of tools in his pocket, and can quickly detach one of the tools from the head and substitute therefor a different kind of tool or tools, and, occasionally, obviating the necessity of carrying a number of tools or pick-heads, for one head it ill do for all of the detachable tools, and, consequently, minimizing the n eight to be conveyed by the operator or miner, beside minimizing the cost of the outfit, for one handle and head vv ill ansu er, for a number of purposes oruses, by merely changing the tools a hen desired.

" It is to be noted that each rib 15 comprises a pair of portions integrally connected at their inner ends, and the portions of each rib taper from their inner ends to their outer ends.

What I claim isi 1. In a device of the character described,

the combination of a head comprising a body providedupon opposite sides ith V-shaped reinforcing ribs and with sockets formed in ltsends, set-screns threaded into the ends and adapted to extend at one end into the sockets, said body provided upon its outer face uith an integral, outwardly-curved or bulged guard spaced from the body intermediate its ends, and said body and guard provided nith registering openings or apertures, the aperture in said body adapted to receive a handle.

2. In a device of the character described, the combination with a handle, of a head positioned upon said handle, said head comprising a body, said body provided ith reinforcing ribs at opposite sides and ith an outwardly-bulged guard upon one face, the guard integral at its ends ith the body and spaced therefrom intermediate its ends.

3. In a device of the character described, the combination of a head provided at its ends with tool-receiving sockets or pockets and upon one side intermediate its ends with an outwardly-curved or bulged guard, the guard being spaced intermediate its ends away from the body.
